I just used my 12V cable for the first time and after 8 hours driving with 12V connected, there was no change in the charge level of the AP. I have had no trouble charging the AP with 240V or solar via Anderson plug (and controller). The ARKPAK 730 was purchased in January 2018. The battery is brand new also and is a Fullriver AGM 105Ah.
I have now completed some basic investigations. I connected the AP in the car with the engine running and watched the LED display for some time. After connection, a short while (minute ?) the display shows Charge cycle at about +50 watts for about a second or so and then immediately goes back to Discharge cycle. After a few more minutes, this repeats ie short period of Charge and then back to Discharge.
I have checked my car's 12V cigarette outlets with a multi-meter and they all show around 14V. I then checked the ARKPAK 12V cable and noted that the output voltage was 11.9V to 12V despite a 14V input. Is this normal or do I have a faulty 12V cable and could this be the cause of the problem?
I am about to depart for a trip to the Gibb River Road from Shark Bay and really need to come up with some sort of solution to this problem as I will definitely need the 12V charging to be working for a successful trip.
